Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and in particular to an LED lighting fixture. Background Technology

[0002] LED lighting fixtures include light-emitting components and a driver power supply that is connected to the circuitry of the light-emitting components. The light-emitting components include a substrate and LED chips on the substrate. Conventional techniques achieve the circuit connection between the light-emitting components and the driver power supply through soldering, which is a relatively complex manufacturing method.

[0003] Chinese patent CN219933850U discloses an easy-to-assemble LED plug-in lamp. In this design, a connector is provided on the substrate, and the driver power supply has pins that mate with the connector. The connector and pins engage to achieve circuit connection between the driver power supply and the light-emitting component, which is easier to process and assemble than traditional soldering methods.

[0004] However, the above technical solution only changes circuit soldering to circuit plugging. When the driver power supply and the light-emitting component are plugged in, the pins of the driver power supply are small and difficult to position accurately in the automated production process. During the automated assembly of various parts of the LED lamp, the pins are prone to misalignment, resulting in a low yield rate of automated processing. Utility Model Content

[0005] Therefore, it is necessary to provide an LED lighting fixture to address the aforementioned technical problems.

[0006] LED lighting fixtures, including:

[0007] The lamp housing includes a tube body, a first sealing member, and a second sealing member. The tube body has an open first end and an open second end, and the first sealing member and the second sealing member are respectively assembled at the first end and the second end.

[0008] A light-emitting component, assembled inside the lamp housing, includes a substrate and LED beads and a connector electrically connected on the substrate, the connector having a slot;

[0009] A driving power supply includes a circuit board and circuit elements disposed on the circuit board. The circuit board includes a base layer, a circuit layer, and a solder mask layer. A portion of the circuit board forms a connector that extends into the slot. The solder mask layer of the connector has a partial opening to expose the circuit layer and form a contact area for electrical connection with the connector.

[0010] The lamp holder is connected to the first sealing member, and the lamp holder has a conductive member for connecting to an external power source and electrically connecting to the driving power source.

[0011] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0012] Optionally, the connector is formed by reducing the width of the circuit board and is located at one end in the length direction.

[0013] Optionally, the contact area is a strip-shaped structure extending along the insertion direction of the connector.

[0014] Optionally, the slot has an electrical connector that is electrically connected to the contact area.

[0015] Optionally, the LED luminaire includes a guide portion that directs the connector into the slot.

[0016] Optionally, the guide portion includes a guide ramp disposed on the plug socket.

[0017] Optionally, the first sealing element has a cavity for accommodating the driving power supply.

[0018] Optionally, the lamp head has a positioning part for positioning the driving power supply.

[0019] Optionally, the positioning part includes a positioning groove adapted to the circuit board, the positioning groove being open at one end toward the first sealing member and closed at the other end.

[0020] Optionally, the lamp holder has a plug-in portion that is inserted into the cavity and fits with it with a clearance, and the positioning groove is disposed on the plug-in portion.

[0021] Optionally, the plug portion is provided with a locking portion that engages and fixes with the first sealing member.

[0022] Optionally, a heat sink is provided inside the tube, the light-emitting component is fixed on the heat sink, and the end of the heat sink is connected to the first sealing member and the second sealing member by screws.

[0023] The LED lamps of this application have at least the following technical advantages: During assembly, the driver power supply can be pre-positioned to the lamp head. During the assembly process of connecting the lamp head to the first sealing component, the connector of the driver power supply extends into the slot of the light-emitting component, completing the circuit connection between the driver power supply and the light-emitting component, and simultaneously completing the connection between the lamp head and the first sealing component. The connection between the lamp head and the first sealing component provides guidance and positioning for the insertion and mating of the connector and the slot, facilitating automated assembly.

[0024] The contact area of ​​the connector in this application is larger than that of traditional pins, resulting in a higher fault tolerance rate for circuit connection. This facilitates automated assembly of LED lamps and improves the yield rate of automated assembly of LED lamps. Attached Figure Description

[0049] See Figures 1-3 One embodiment of this application provides an LED lamp, including a lamp housing, a driver power supply 100, a lamp holder 200, and a light-emitting component 300.

[0050] See Figures 2-4 The driving power supply 100 includes a circuit board 110 and a connector 101 and a pin 102 disposed on the circuit board 110. The driving power supply 100 also includes circuit elements 103 disposed on the circuit board 110. The circuit elements 103 constitute rectifier circuits, filter circuits, and power conversion circuits, etc., for converting external AC power into DC power to supply power to the light-emitting component 300. The pin 102 is used to receive AC power, and the connector 101 is used to provide DC power to the light-emitting component 300.

[0051] See Figure 4 The lamp holder 200 has a conductive element 210 for connecting to an external power source and electrically connecting to a drive power supply 100, such as AC mains power. The conductive element 210 is electrically connected to a pin 102. Specifically, the conductive element 210 is a hollow post 211 with at least one end open to the pin 102. The hollow post 211 has an opening 212 open to the conductive element 210 for the pin 102 to be inserted, facilitating circuit connection. The lamp holder 200 may be, for example, model G23.

[0052] See Figures 2-5The light-emitting component 300 is assembled and fixed inside the lamp housing. The light-emitting component 300 includes a substrate 310, LED beads 320 electrically connected to the substrate 310, and a connector 330. The connector 330 has a slot 331. The connector 330 is used to connect with the connector 101. During assembly, the connector 101 extends into the slot 331.

[0053] See Figures 4-6 The lamp housing includes a tube body 400, a first sealing member 500, and a second sealing member 600. The light-emitting component 300 is assembled and fixed inside the tube body 400. The tube body 400 is a one-piece molded structure with an open first end 401 and a second end 402. The first sealing member 500 and the second sealing member 600 are respectively assembled to the first end 401 and the second end 402 to close the tube body 400. The first sealing member 500 is connected to the lamp holder 200 and has a cavity 511 for accommodating a driving power supply 100. The inner wall of the cavity 511 is provided with a mounting groove 512 for accommodating the circuit board 110 of the driving power supply 100.

[0054] See Figure 4 A heat sink 700 is disposed inside the tube body 400. The two ends of the heat sink 700 are connected to the first sealing member 500 and the second sealing member 600 respectively via screws 701, facilitating automated assembly of the tube body 400 and the two sealing members. The light-emitting component 300 is fixed to the heat sink 700, indirectly assembled and fixed inside the tube body 400. A first sliding groove 403 is provided inside the tube body 400 for sliding installation of the heat sink 700. The heat sink 700 is specifically made of metal, such as aluminum. A second sliding groove 710 is provided in the heat sink 700 for sliding installation of the substrate 310. The tube body 400 has a length direction extending between the first end 401 and the second end 402, and a width direction perpendicular to the length direction. The first sliding groove 403 and the second sliding groove 710 respectively restrict the movement of the heat sink 700 and the substrate 310 in the width direction of the tube body 400.

[0055] As a fixing method, the radiator 700 has mounting holes 720 at both ends along its length. The mounting holes 720 can be opened through the length to form through screw slots. The first sealing member 500 and the second sealing member 600 are connected and fixed to the screw slots at both ends of the radiator 700 by screws 701. The first sealing member 500 and the second sealing member 600 abut against the first end 401 and the second end 402 of the tube body 400, respectively, to fix the tube body 400, the two sealing members, and the radiator 700.

[0056] See Figures 4-6Furthermore, the first sealing member 500 has a first limiting plate 510 located at the first end 401 of the tube body 400, which is used to position the tube body 400. The second sealing member 600 has a second limiting plate 610 located at the second end 402 of the tube body 400. Both the first limiting plate 510 and the second limiting plate 610 have screw holes 404 for screws 701 to pass through and be fixed to the heat sink 700. The substrate 310 of the light-emitting component 300 is clamped and fixed between the first limiting plate 510 and the second limiting plate 610, thereby assembling and fixing the light-emitting component 300, so that the slot 331 of the light-emitting component 300 has a defined relative position with respect to the first limiting plate 510.

[0057] The second sealing component 600 includes a separate second limiting plate 610 and a decorative cover 620. The second sealing component 600 with the decorative cover 620 has a smooth and flat surface, improving its aesthetics. The second limiting plate 610 has a first engaging component 611 on the side away from the pipe body 400, and the decorative cover 620 has a second engaging component 621 facing the second limiting plate 610. The first engaging component 611 and the second engaging component 621 can be mutually cooperating holes and protrusions, used to achieve the engagement and fixation of the second limiting plate 610 and the decorative cover 620.

[0058] The LED lamps provided in each embodiment can be used as plug-in lamps. Since the light-emitting component 300 is assembled on the tube body 400 and the first sealing component 500 is assembled on the first end 401 of the tube body 400, the first sealing component 500, the light-emitting component 300 and the tube body 400 are assembled and fixed together, and thus the slot 331 on the light-emitting component 300 has a relatively unique position relative to the first sealing component 500.

[0059] See Figure 7 The lamp holder 200 has a positioning part for positioning the driving power supply 100. The positioning part includes a positioning groove 222 adapted to the circuit board 110. The positioning groove 222 is open at one end facing the first sealing member 500 and closed at the other end. The lamp holder 200 has a plug-in part 220 that is inserted into the cavity 511 and has a clearance fit with it (forming the inner wall of the cavity 511). The plug-in part 220 is specifically a cover formed by the lamp holder 200 itself extending towards the tube body 400. The positioning groove 222 is specifically provided in the plug-in part 220. The plug-in part 220 is engaged and fixed with the first sealing member 500. Specifically, the plug-in part 220 is provided with a locking part 223, and the inner wall of the cavity 511 of the first sealing member 500 is provided with a locking part 530 that engages with the locking part 223. The locking part 223 can be, for example, a slot, and the locking part 530 can be, for example, a protrusion that engages with the locking part 223. After the insertion part 220 is inserted into the cavity 511, the engaging part 223 engages with the engaging part 530 to achieve the engagement and fixation of the lamp holder 200 and the first sealing member 500.

[0060] See Figure 7 and Figure 8 The circuit board 110 of the driving power supply 100 includes a base layer 111, a circuit layer 112, and a solder mask layer 113. A portion of the circuit board 110 forms a connector 101 extending into a slot 331. Specifically, the connector 101 is formed by narrowing the circuit board 110 in the width direction and is located at one end in the length direction. The length direction of the circuit board 110 is the same as the length direction of the tube body 400, specifically the insertion direction of the connector 101 into the slot 331. The solder mask layer 113 of the connector 101 is partially exposed by openings to form a contact area 104. The contact area 104 is a strip-shaped structure extending along the insertion direction of the connector 101 into the slot 331. The slot 331 is electrically connected to the contact area 104. The slot 331 has a contact surface 333 facing the contact area 104. The contact surface 333 is provided with an electrical connector (omitted in the figure) for electrically connecting the contact area 104 to realize the electrical connection between the driving power supply and the light-emitting component. The LED lighting fixture includes a guide portion that guides the connector 101 into the slot 331. The guide portion includes a guide ramp 332 disposed on the connector 330. When the connector 101 contacts the guide ramp 332, it is guided into the slot 331 by the guide ramp 332.

[0061] See Figure 9 During assembly, the driving power supply 100 can be pre-positioned to the lamp holder 200. Then, the plug-in portion 220 of the lamp holder 200 is plugged into the first sealing member 500. The driving power supply 100 then enters the cavity 511 of the first sealing member 500. Under the plugging engagement, the plug 101 of the driving power supply 100 extends into the slot 331 of the light-emitting component 300, thus completing the connection between the lamp holder 200 and the first sealing member 500. In this process, the connection between the lamp holder 200 and the first sealing member 500 provides guidance and positioning for the plug 101 to be plugged into the slot 331, facilitating automated assembly. Furthermore, the guide slope 332 provides guidance and positioning for the plug 101, so that the plug 101 is guided into the slot 331 of the light-emitting component 300.

[0062] In the various embodiments of this application, the connector 101 and slot in the LED lamps are connected by a plug-in joint, so that the contact area 104 and the contact surface 333 are electrically connected. Compared with the traditional circuit pin connection, the circuit contact surface is increased, the fault tolerance of the circuit plug-in is higher, it is convenient for automated assembly of LED lamps, and the yield rate of automated assembly of LED lamps is improved.

[0063] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0064] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
